3' Claims.

The present invention relates, to a ration point tally and moreparticularly to the means for rotatably mounting such a tally.

At the present time the conventional metal eyelet which is ordinarilyemployed as a means for providing a pivot about which a disk may rotate,in making computations as well as for other use ful purposes, is nowless available for such use owing to the demand for metal vital to thewar effort, and to provide a substitute pivot means whereby theoperation of the disk is'not impaired,

but on the other hand improved, is one of the major objects of thisinvention.

Other important objects include: the provision of an invisible pivot forrotating indicating disks or rotating disks in general; the provisionof. a novel combination ration card holder and ration point tally; theprovision of a novel cover including integral fingers for rotativelyattaching the disk to the cover; the provision of a novel cover foldablein such a manner as to provide a novel locking means for holding theintegral fingers in their deflected disk supporting positions; theprovision of a disk rotating axis having spaced peripheral points, of

contacts for supporting the disk rotatively therea device having anindicating disk which may be set to show some numerical value and whichis turnably supported without the use of any pivot means whatever, thearticle when thus constructed being suited for use as an advertisingnovelty to be given gratuitously to patrons and prospective customers byvarious merchants.

Other objects, advantages and features of invention will hereinafterappear. In the accompanying drawings wherein is shown what is nowconsidered preferred embodiments of the invention;

Fig. 1 is a front assembled view of one embodiment of the invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a plan viewof the device in its extended unfolded condition.

Fig. 4 is a view similar to Fig. 3 showing the first step in the foldingoperation, which, step shows the integral pivot forming fingers lockedin their deflected operative positions.

Fig. 5 is an interior open view of a second embodiment of the invention.

Fig. 6 is a section taken on line 5-8 of Fig. 5.

Fig. 7 is a perspective View of the cover shown in Fig, 5 in a slightlyfolded condition with the rotating disk phan-tomally outlined in itsoperative position.

Referring in detail to the drawings, the cover portion of the device, asshown in the first four views, is made of a senii-rigid sheet material,for example, of a medium weight cardboard. Said cover portion comprisesthe flap 9 which carries the rotatable disk iii; the window containingflap or section 5 l and the stabilizing back flap l2.

Said disk-carrying flap I9 is shown having through it a central,circular aperture M. At the time this. aperture is punched out a part ofthe sheet material within its circumference is cut in such a manner as,to form one or more fingers or ears I-5 (four in the illustratedembodiments), these fingers, are therefore, integral with the covermember, and if plural in number, are all turned back adjacent to thesame face of the flap 9 and cooperate to form a pivot means to rotatablyattach the disk It to the flap 9. Said fingers are grouped around acommon center and should be circumferentially spaced apart at equaldistances from each other.

It is not essential that so much of the flap 9 be cut away as to formthe complete circular opening shown, but is suflicient if rectangularextensions of the sheet material or cardboard be cut which are largeenough to form said ears or fingers. l5.

The. disk Ill has at its center a circular opening Illa of about thesame diameter as the opening l4 through the flap. 9., and before thefingers I5 are turned back the disk and flap are contacted in aface-to-face manner with their apertures registering, with each other,and then the fingers are turned back in an overlying relation to thedisk to form a pivot therefor.

The window flap II is so called because it is provided with a window orsight opening ll through which rows l8 and IQ of numerals inscribed onthe disk may be read.

The flaps 9 and H are foldably joined along the fold line 2!, the edgeportion of the cover, being cut away at 22 thus forming a notch at eachend of said line, this facilitating the folding over of the flap 9 uponthe adjacent section ll of the cover, whereupon said section retains thefingers E5 in a constricted space in their down bent position causingthem to form a dependable pivot means for the disk.

At the juncture of the fiap or section II with the stabilizing flap orsection 12 there is a fold line 25 at each end of which the cover hascut into its edge a notch 25. Along the midlength portion of this foldline extends a slit or narrow slot 21 through which is projectable asmall segment of the circumference of the disk It] when the cover is inthe folded condition shown in Fig. 2, this projecting part of the diskenabling the user to rotate it manually in the step-bystep fashionrequired to progressively step up the numerical values indicated by thenumerals thereon as seen through the sight opening l1. It is to beunderstood that the cardboard or other sheet material of which the coverportion of the device is made will be sufficiently resilient to enablethe assembler to spring the slotted edge portion of the cover over thepart of the mounted disk IE! to be exposed when the flaps 9 and H arefolded together with the disk between them.

The combined cover sections 9' and H may be regarded as constituting atwo-part end flap which is joined to the remaining portion of the covermember along the fold line 25, and when the folding up of the coversections 9, II and I2 has been accomplished the disk is securelymaintained in its mounted, operative position, with a segment of itsperiphery projecting through the slot 21 and with the numbers containedin each of its number rows I8 and I9 positioned for being displayed oneat a time through the sight opening l1. After the user has kept tallyfrom unity to 50 by turning the disk as required and then observing thenumerals in the outer row I9, then he or she will observe the numeralsof the inner row [8 for tallying from 51 to 100-. A glance at the partlyused up ration book will enable the user to determine without difficultywhich of the two rows of numbers is to be consulted to determine thenumber of ration points which have been used.

The cover sections II and I2 are shown as being of substantially equalwidths, but the diskcarrying flap 9 is preferably slightly tapered fromits attached to its free edge, as shown in Fig. 3.

The window section I I is furnished at each side of the cover structurewith a relatively narrow infoldable fiap 28, these flaps each beingshown symmetrically positioned in relation to the said section I! andnot quite as long as the width thereof. When the cover structure is inits folded up condition these narrow flaps form abutments between whichthe disk I0 turnably fits, the envelope structure thus provided beingcompleted by adhesive applied to the faces of the flaps 28 opposite tothat shown in Fig. 3.

In Figs. 5, 6 and '7 is shown another embodiment of the inventionwherein a case or wallet adapted to contain ration books is'combinedwith the number disk. In these views the construction of the disk In isthe same as that already described and therefore the various partsthereof are numbered in the same manner. In the completed article an endflap 30 to which the disk is pivoted, is folded so as to be adjacent tothe inner side of the window section 31. When the article is open asshown in Figs. and 6 said window section forms the front outer wallthereof, and the middle section 32, of which said section 3| is acontinuation, forms the back wall of the wallet. From the opposite edgeof the section 32 extends a section 33 that carries a flap 34, thusforming a pocket 35.

The completed article shown in Figs. 5 and 6 has a stitched on selvagestrip 36 along each end section 3|.

I thus completing a pocket 3'! back of the number disk, as well as thealready mentioned pocket 35. Along the free edge portion of the end flap34 is shown an inwardly folded flap 38 which is stitched down to form aselvage.

In Fig. '7, where the one-piece wall member of the wallet is separatelyshown in a partly folded condition, the ivot-forming fingers 40 areshown in their unbent condition, these same fingers appearing in Fig. 6in their bent over position forming a pivot for the disk l0 and beingretained in their bent over position by the overlying wall In this vieware shown a slot 4| and a sight opening 42 which function the same asthe slot 21 and sight opening I! already described.

It will be seen most readily in Fig. 6 that when the article is in itscompleted condition, the pocket 31 has a front wall which is free fromany internal projection, whereas, if the indicating disk were furnishedwitha pivot forming eyelet an end of such eyelet would necessarilyproject into the pocket in an objectionable manner.

It will be seen that, in both illustrated embodiments of the invention,one of the pivot-forming fingers is positioned at that side of thepivotforming structure which is nearest to the slot through which anedge portion of the indicating disk projects, so that such finger willreceive, in a direct and flatwise manner, the pressure against the diskproduced by the manual turning thereof. Hence the disk may be so mountedthat the edge portion thereof opposite to its projecting segment is keptout of frictional contact with the casing or wallet.

It should be understood that the present disclosure is for the purposeof illustration only and that this invention includes all modificationsand equivalents which fall within the scope of the subject matterclaimed.

What is claimed is:

1. The combination, with a disk having a centrally apertured portion; ofa mounting member for said disk carrying a plurality of fingers or earswhich extend through the aperture of said disk and are outwardlydirected from a common center to overlie the portion of the diskcircumjacent to its aperture to attach said disk pivotally to saidmember, said mounting member consisting of a semi-rigid sheet materialand said lingers being integral therewith; and a supporting member ofwhich said mounting member is a continu ation and against which it isfoldable to a position wherein said fingers are interposed between saidtwo members and are thus maintained in their pivot'forming relation tosaid disk, said supporting member and said mounting member invisiblyenclosing between them said pivot fingers when the device is in thecompleted condition.

2. In a device of the kind described, a cover member consisting ofsemi-rigid sheet material and having an end flap which is foldable uponit, a plurality of fingers carried by said fiap,'said fingers beinggrouped around and directed radially outward from a common center whichis located at a point spaced considerably inward from edge portions ofsaid flap, and a disk having a central aperture through which saidfingers extend to form a pivot upon which said disk is rotatable, saidflap and cover member being foldable along a fold line between them intoa juxtaposed postion wherein the cover member engages said fingers tokeep them in a deflected pivot forming condition.

3. In a ration point tally, a cover member consisting of a strip ofsemi-rigid sheet material and having a two-part end flap joined theretoalong a transversely extending fold line, the two parts of said end flapbeing joined by a fold line for folding upon each other, and means tomaintain said flap in said folded over position, said cover memberhaving a plurality of fingers consisting of portions of the sheetmaterial thereof, said fingers being bent over and directed outwardlyfrom a common center and said disk having a central, pivot aperturethrough which said fingers eXtend to pivotally attach the disk to thecover member, said fingers being maintained in a bent over pivot-formingposition by reason of the constricted space which they occupy betweensaid flap and the remaining portion of said cover member.
